not really bro, they come with a median that really grabs a lot,
ive tryed all three choices,i ll call them 1-2-3, the 1 was rediculous
it cut the cfm on a 120 in half, the 2 was almost the same, the third was
really the deal,my server and my gamer rig i haven t had to clean since,
but the filters i do every other week, i think if your serious about the longevity
of your hardware their the cheapest insurance you can buy,but i do agree with you
anything you use is better than nothing,
